Large varicose veins on head
When veins become bulging, such as yours, those are called varicose veins. When they become Too large, laser treatments are often times not as effective as removing them using a procedure called ambulatory phlebectomy or microphlebectomy. This is where the area around the vein is numbed and a tiny incision is used to remove the vein with a small hook. I can't tell if that is an option for you from your pictures. I would perhaps consult with an ENT physician/neurosurgeon/vascular surgeon. Insurance should cover this for you if there are symptoms associated with it.
The posted pictures look like arteries rather than veins. Arteries pulsate and veins do not. If in doubt, a duplex scan can distinguish between the two. If these are arteries then I would leave them alone. If these are veins then they can be treated by removal through tiny incisions (microphlebectomies) but you will be trading a vein for several small scars. See a vein specialist or a vascular surgeon.
